I have been following the threads on both PowerOp and OpPoint; however, I
never thought they would do the job of voltage/power/clock domain
frameworks. The way I interpreted is that they _need_ the domain frameworks
so that they could handle lower-level physics better.

I have requirements and some very rough ideas. And I was searching for an
existing implementation or a discussion so that I can find a place to start
with. Maybe we can start by writing down the requirements. As far as I know,
the CELF PM Requirement document does not have a section for voltage/power
domain frameworks.
